In my previous post in the 5G NR RAN series, I showed how to decode the PDCCH (physical downlink control channel), which is used to send control information from the gNB (base station) to the UEs (cellphones). In this series I am using as an example a short recording of the downlink of an srsRAN gNB. The PDCCH transmission that I decoded in the previous post was a DCI (downlink control information) containing the scheduling of the SIB1 PDSCH transmission. The PDSCH is the physical downlink sh...| Daniel Estévez
MOVE-II is a cubesat from Technical University of Munich that was launched in December 2018. It transmits telemetry in the 145 MHz amateur satellite band using a protocol that uses CCSDS LDPC codewords. Back in the day, there was a GNU Radio out-of-tree module developed by the satellite team to decode this satellite. Given the additional effort required to support LDPC decoding for just this satellite and since there was already a GNU Radio decoder available, I never added a decoder for MOVE-...| Daniel Estévez
